just installed walkway with tumbled Pavers from a company called Nare (sp?) or something like that. Either way, they've been in for 2 weeks now and of course look all dirty which the owner does'nt like. The homeowner wants me to seal the pavers now but I've heard different companies say you should wait 6 weeks to 6 months before sealing. Customer is on me to seal now. Should I do this? Any possible problems that could happen? The alternative would be to wait months as the owner will hold back cash. Please let me know your thoughts. Wondering what your experiences have been in similar situations. Thanks.
